Answer:

P(A)= probability of who passed maths

=140/200

P(B)= probability of who passed Sci

= 120/200

P(A&B)=(140+120-200+40)/200

P(A|B)'=40/200

Answer:

n(U)=200

n(M)=140

n(S)=120

n(MuS)complement=40

n(MuS)=n(U)-n(MuS)complement

=200-40

=160

n(MnS)=n(M)+n(S)-n(MuS)

=140+120-160

=260-160

=100

2x=3y+1/2 I have to write this in standard form and slope intercept form
Sav [38]

Answer:

Step-by-step explanation:

2x = 3y + 1/2

standard : Ax + By = C

2x = 3y + 1/2....multiply everything by 2 to get rid of the fractions

4x = 6y + 1 ....subtract 6y from both sides

4x - 6y = 1 <==

slope intercept : y = mx + b

2x = 3y + 1/2....subtract 1/2 from both sides

2x - 1/2 = 3y....divide everything by 3

2/3x - 1/6 = y...rearrange

y = 2/3x - 1/6 <===

An item is regularly priced at $80. Juan bought It at a discount of 20% off the regular price. How much did Juan pay?
Gnesinka [82]
Hello there! So, the item has a 20% discount, but Juan still had to pay 80% for the item. To find the amount he paid, all you have to do is multiply the price by the percentage. We multiply by 80%, because he still had to pay the portion of the price. 80 * 80% (0.8) is 64. The. Juan paid $64.

Determine the radius of a circle if a 24-inch chord is 9 inches from the center.
bixtya [17]
Hi! :)

The radius of a circle is the length from the perimeter of the circle to the center of the circle. 

If  24 inches is still 9 inches from the center, you just have to add 24 and 9 to get the radius. 

24+9= 33

Your final answer should be that the radius is 33 inches.

Hope this helps!
